Its a 355 with a 4l80e trans. There are picks of the engine in the engine pick thread. At some point and time I am going to build a new set of headers to go with the engine. I am building a 400ci bowtie block with billet caps, callies crank, howards billet rods, je pistons, solid lift billet rolller, with the dart pro 1 heads I have now but they are going to be cnc ported.
